py-mpmath: updated to 1.1.0


* Fixed severe bug in householder() for complex matrices
* Fixed frequently-reported bug where findroot() mysteriously raised
* Corrected rounding in binary-to-decimal conversion above 500 digits
* Fixed minor loss of accuracy affecting rf(), ff(), binomial(), beta()
* Fixed incorrect computation of the Hurwitz zeta function in some cases
* Fixed accuracy of digamma function near 0
* Fixed RuntimeError in qfac() in Python 3.7 caused by raising
* Fix to allow NumPy arrays in fdot()

Features and improvements:
* Added more automatic conversions from Fraction, Decimal, NumPy types
* Support creating mpf from a long literal
* Implemented log1p()
* Slight speedup of eig()
* Implement polylog() for general complex s and z by using Hurwitz zeta
  algorithm as a fallback

* Test more CPython and PyPy versions
* Drop support for Python 2.6 and 3.2
* Use py.test for test code; lots of code cleanup
* Corrections to the documentation

py-mpmath: updated to 1.0.0

* Bumped to major version number for 10 year anniversary
* Added module for inverse Laplace transforms, including the top level
  function invertlaplace() as well as several different algorithms
  (Talbot, Gaver-Stehfest and de Hoog) implemented in
  mpmath.calculus.inverselaplace (Kris Kuhlman)
* Fixed bugs in elliprg() giving incorrect values for certain input
* Fixed wrong degree 1 nodes for Gaussian quadrature
* Made make acot(0) and acoth(0) return a finite result
* Fixed sieved zeta sum not being used in Python 3, and added cutoff
  for sieved zeta sum on 32-bit systems when too much memory would be used
* Fixed zeta(0,0.5) to return correct value instead of raising
  NoConvergence exception
* Added detection of exact zeros in gammainc(), in particular fixing
  NoConvergence error for gammainc(3,-1+1j)
* Fixed wrong values from besseli() due to improper internal precision
* Fixed bessely(0,1j) to return complex nan instead of raising NameError
  (Paul Masson)
* Changed float() and complex() applied to an mpf or mpc to use rounding
  to nearest (or the context rounding mode) instead truncating
* Fix imaginary part of gammainc(n,x), n negative odd int, x < 0
* Added alternative "phase" color scheme to cplot()
* Better error message for int(inf) or int(nan) (Aaron Meurer)
* Fixed polyroots() with error=True
* Added support to pass optional initial values to polyroots()
  (Michael Kagalenko)
* Rewrote the Python major version selection to make it work if something
  else has redefined xrange (Arne Brys)
* Switched documentation formula rendering to MathJax (Sergey B Kirpichev)
* Fixed documentation TeX build (Sergey B Kirpichev)
* Added PEP8 conformity testing (Sergey B Kirpichev)
* Various fixes for the test code and test infrastructure on different
  platforms and Python versions (Sergey B Kirpichev)
* Fixed module paths in setup.py (Aaron Meurer)
* Documented more options for methods such as nstr() and hyper()
* Miscellaneous corrections to the documentation (various)
